File error: data may have been lost
 

Environment: Windows XP/ 2000, Office 2000 SP 3, Patch: kb923274

Excel workbook containing several sheets, which has macros, controls,
hyperlinks etc., We are able to open the file for the first time. got to save
it and close the application. Reopening pops up the error "File error: data
may have been lost" clicking OK several times gets to the application but
without the controls.
This happens only after installing the patch.

Also tried after removing all the macros, but the problem persists.
